Like every summer, sunscreen is still a hot topic this year – and rightly so! Since it is profitable to lubricate well in the long term, you can not stress enough – to effectively prevent sunburn, skin cancer and premature aging of the skin. However, do not forget to pay special attention to the choice of sunscreen. According to science, some ingredients are potentially dangerous – and enter our circulation faster than expected.
New study: sunscreen quickly enters the blood
The American study "Effect of the application of sunscreen under maximum use conditions on the plasma concentration of the active ingredients of sunscreen published in the newspaper "Jama" examined the time needed to detect the chemicals contained in sunscreens in the blood. For the study, the urine and blood of 24 study participants were tested for the chemicals avobenzone, oxybenzone, ecamsul and octocrylene, which act as UV filters. The results show that the 4 could still be detected after 24 hours. Values were so high that new investigations of potential hazards were ordered. "We need studies to classify these findings and determine if the absorption of certain ingredients has real health effects."Said Dr. David Leffell, spokesman for American Academy of Dermatology in an interview with CNN.
What are the alternatives?
According to the study, sunscreens can be used to prevent these chemicals no chemicals but physical filters included. The difference? The nanoparticles of these latter reflect and / or disperse the sunlight and thus remain on the surface of the skin, instead of penetrating and entering the blood.
